In an effort to compare the halogenated tyrosine derivatives from Desmospongiae Makarieva et al. (149) investigated 22 species of eleven Demospongiae families and identified 10 substances of this type in Aplysina (Verongia), Verongula, and Aiolochroia species. It has been shown that animals of the Aplysinidae family biosynthesize all three forms [(-I-), (—), (+) = racemate] of aeroplysinin-1 (233) and of an... [Pg.184]

Gao et al. reported araplysillin-III (103) and hexadellin C (104) from the sponge Aiolochroia crassa 36). The absolute configuration of the spiroisoxazoline of both alkaloids was determined by CD spectra. The absolute configuration at C-18 of araplysillin-IIl (103) was shown to be l by HPLC analysis according to Marfey s procedure. The configuration of the A, iV,iV-trimethylhomoserine moiety was deduced as L by comparison of the optical rotation with the d- and l- standards. [Pg.73]

A methylation derivative of aerophoin-2, Af-methyl-aerophobin-2 (115), was isolated from a Caribbean sponge specimen of Aiolochroia crassa 87). [Pg.75]
